Yes, ICDPPCNEXUS will be a pretty reliable debugging option for MPC5777C. The only feature that I think we lack is support for uncensoring the chip. My colleague who works on this product is currently on vacation. When he returns, I will ask him if this is still the case.

The performance between the USB-ML-PPCNEXUS and USB-ML-UNIVERSAL will be similar. The USB-ML-UNIVERSAL-FX runs at a much higher speed and is where you will really see a difference especially on devices like yours with large flash sizes.

In a separate post from November 7, 2014 Takao Yamada stated: "We are in alpha development on getting a GDB debugger for Freescale's Qorivva chip... The estimate time of release is end of Q2 of next year."

We would _really_ like to use GDB with 5777C, is there any update on this? I noticed you now have GDB support available for ARM but can't find anything for PPC.

You need to download S32 E200, not S32 ARM. Very different products. Please check the NXP website for the latest download of S32 E200 and everything will work with MPC5777C with any hardware we sell and support Qorivva.
